CAR-TRUCK.

SPECIFICATION forming part 4of Letters Patent No. 596,449, dated December 28, 1897.

Application iiled March 3, 1897. Renewed December 6, 1897. Serial No. 660,985. (No model.)

To all whom it may concern.:

Be it known that I, RICHARD W. OsWALD, a citizen of the United States, residing at Bloomsburg, in the county of ColumbiaJ and State of Pennsylvania, have invented certain new and useful Improvements in Car-Trucks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to car-trucks and it consists in the combination, with a bolster, of side frames comprising upper and lower T- irons forming arch-bars for supporting said bolster and pedestals in said side frames.

It also consists in the combination, with a bolster, of side frames comprising T-shaped bars for supporting said bolster, the said T- bars being formed into pedestals at their ends for receiving the journal-boxes of the truck.

It further consists in certain other novel constructions, combinations, and arrangements of parts, all of which will be hereinafter fully described and claimed.

A. In the accompanying drawings, Figure l is a plan view of one side of my improved cartruck. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse vertical section of the same, portions of the truck being shown in elevation. Fig. 4 represents a detail elevation of an improved form of pedestal used in my improved car-truck. Fig.v 5 is a detail end view of the same.` Fig. 6 is a detail cross-section of the T-shaped bars,no brace or spreader being'interposed between them. Fig. 7 is a similar view showing the T-shaped upper bar and a channel-iron for the lower bar. Figs. 8 and 9 are similar views showing bars of different shape in cross-section which I contem plate using in connection with my car-truck, no spreader being shown between the bars in these constructions.

A in the drawings represents a car-truck constructed in accordance with my invention.

B is a bolster, C the side frames, and D D pedestals.

Each side frame C of the car-truckis preferably constructed by forming an arch o of a T-shaped bar and an inverted arch o also of a T-shaped bar. The T-shaped bars have broad horizontal flanges o9 and vertical ribs or webs, as o8. These arch-bars o o converge toward points near the pedestals, at which points they nearly meet. The upper bar o then passes in an upward direction over the journal-boxes F F and pedestal-springs f f and thence downwardly in a vertical line to form one side of the pedestals. The other side of each pedestal is formed by bending downwardly the ends of the lower arch-bar c'. The ends of these bars c c are preferably connected at a point beneath the journal-boxes F F by bolts c2, passing through their ends and through spacing-sleeves c3. The braces or spreaders o4 c4, consisting of metallic pieces of angular shape to iit in the angles formed between the bars c o' and the pieces c5 c5, are preferably interposed between the arch-bars at the points where they come close together. In order 'to strengthen the pedestals, U- shaped pieces c5 c5 of metal are bolted to the inner surface of the angle-bars forming said pedestals. bars c o and the braces or spreadersc4 c4 are all firmly secured together by riveting or other securing means. The journal-boxes F F are of any ordinary type and are adapted to receive springs ff upon their upper sides for supporting the side frames upon the journals, and cap-piecesc c6, having upwardly-extending flanges c7 c7, are interposed between the springs and the upperv part of the pedestals, forming a broad bearing for the said side frames.

The bolster or transom B is preferably formed of channel-bars or I-beams b b, which are secured to the side frames at their central points. The I-beams b b are preferably allowed to extend beyond the side frames, and gusset-plates b' b' are interposed between the upper surface of the I-beams l) b and the lower surface of the arch-bars c c. These gusset-plates are securely bolted or riveted to the flanges or Iebeams and the flanges of the T-irons forming the arch-bar o, and by eX- tending them to the braces c4 o4 they strengthen the arch. I iind that the extending of the I-beams beyond the side frames and the securing of the gusset-plates thereto forms a very strong construction and assists materially in keeping the truck perfectly square.

These pieces c5 c5 and the angle- IOO To the central portions of the I-beams Z9 b is secured the usual center plate b2 for receiving the weight of the car-body. The I-beams b h are preferably braced and connected together by interposing cross I-beams b3 and bolting or riveting them iirmly to the webs of the said I-beams b ZJ. These braces b3 b3 are preferably located beneath the center plate in the middle of the truck and in line with the side frames at either end of the bolster or transom B.

While I prefer to use T-shaped bars for my side frames, as illustrated in cross-section in Fig. 6, I do not wish to limit myself to this construction, for I contemplate using T-shaped bars in connection with channel-bars, as shown in Fig. 7; also, I may use double-T- shaped bars, as further illustrated in Figs. 8 and 9, without departing from the spirit of my invention.

Figs. 6, 7, 8, and 9 of the drawings, just referred to, show cross-sections of modified forms of bars in which the spreader c4 is omitted, the sections being taken where the upper and lower bars would touch each other adjacent to a pedestal.

In Figs l and 5 of the drawings I have illustrated the manner of using divided pedestals in connection with my improved car-truck. In these views the upper and lower arch-bars g g meet above the pedestals and are secured together in a suitable manner at that point. The pedestal G is formed of divisible parts g2 g3, each having sleeves g4 at their upper ends, whereby they are adapted to be slipped onto the ends of the two arch-bars. The inner member g2 of the pedestal is preferably permanently secured by rivets or otherwise in position upon said arch-bars, while the outer member g3 is removably secured by removable bolts or otherwise to the outer ends of the said arch-bars. A suitable space is left between the members of the pedestal G to receive the j ournal-boxes and pedestal-sprin gs. The lower ends of the members g2 g3 of the pedestal G are preferably connected together and braced by a tie-rod g5.`

From the above description it will be apparent that by my simple arrangement of T- shaped bars I am enabled to construct cartrucks of very great strength. The arch-bars by means of their vertical legs o8 possess great strength to take the vertical strain, and

Vthe pedestals are thoroughly fortilied against the back or forward thrust of the wheels and journals, while on the other hand the broad horizontal flanges c9 are competent to receive all lateral thrusts and strain.

Car-trucks constructed in accordance with my invention are not only possessed of great strength, but are extremely simple as well as cheap in construction, and can be readily made with the usual appliances and stock found in railroad-car shops.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is v l. In a car-truckpthe combination with a bolster, of side frames comprising bars having a horizontal member and one or more vertical ribs or webs forming arch-bars for supporting said bolster and pedestals formed between the ends of the said bars, substantially as described. l

4. In a car-truck the combinationI of side frames comprising bars having a horizontal member and one or more vertical webs, forming arch-bars secured together near their ends, their ends being bent downwardly to form pedestals for engaging the journal-boxes of the car-truck, substantially as described.
